K-SEAL Leak Stopping Additive 236 ml.

K-Seal Leak Stop Additive is multifunctional. It permanently repairs leaks in the head, head gasket, block, radiator, heater core, water pump housing, and freeze plug.
K-Seal has a ceramic formula and does NOT contain sodium silicate. K-Seal will not damage the vehicle's cooling system.
This additive is fully compatible with ALL types of antifreeze and additives.
To use K-Seal, it is not necessary to drain or flush the cooling system.
K-Seal can be used with a cold or hot engine (when safe).
K-Seal Leak Stop Additive should be in every car's emergency kit. It allows you to repair the cooling system faster than changing a tire. After the repair is complete, there is no need for additional applications of the additive – you can drain/flush the cooling system without using K-Seal again.
